RE: HVLP painting equipment and robots



It takes too much time to clean between colors.  Waste powder paints can be in 
excess of 400 pounds per day for some operations.  Some pigments may have metals 
in them - metallic colors.  Except for automotive, most people change colors 
frequently rendering the recycle option useless.  Vendors stress the removal of 
VOC's from the air and do not tell about the solid and hazardous waste streams 
that are now created.  The solids must be tested for TCLP.  How often do we 
recommend changes without considering the consequences of the alternative?
